Sometimes my hands get shredded and I need a pair of gloves. I also need a proper vegan power lifting belt to protect my messed up core. I checked Vegan Essentials but didn't find anything, did I miss it?

Powerlifting belts aren't for protection. They increase internal pressure giving you something to "push off" of and therefore lift more, and only work effectively when you learn to hold a deep breath in your stomach. If you learn to do this without a belt and keep your abs tight, that will protect your lower back (along with loading smartly and not attempting weights you shouldn't be lifting).

If your form sucks or you're attempting something stupid, you're going to get injured - belt of not.

Personally I wouldn't bother with one till you're squatting about 1.5x your bodyweight and deadlifting about 1.5 - 2x times with good form and full range of motion.

As for gloves - I found a very decent pair in a regular sports store, simply checked the material.Lots of them are made of synthetic breathing fabrics now. Mine were made by Nike, got it quite cheaply in some outlet.
